When do silkworms appear?
The most common silkworm, also known as silkworm, is one of the economic insects that cocoon on mulberry leaves. Silkworm originated in China, its development temperature is 7-40℃, and its suitable feeding temperature is 20-30℃.
Silkworm has experienced silkworm eggs, ants, mature silkworms, cocoons and moths for more than forty days in its life.
The newly hatched silkworm babies are as black as ants, and we call them "ant silkworms". Their bodies are covered with fine hairs, which will not be obvious in about two days. Silkworm ants will have an appetite about 40 minutes after hatching, and then start the feeding process.
Silkworm babies feed on mulberry leaves After eating mulberry leaves continuously, the body gradually turned white and began to peel after a period of time. When peeling, they don't eat or move for a day or so like sleeping. This is called "dormancy". Once skinned, it is the second instar larva. Even if they skin it once, it will add a year. * * * They will be skinned four times before they become fifth instar larvae and start spinning cocoons.
It takes two days and two nights for five-year-old larvae to cocoon, and the longest silk used for cocoon can be pulled 1.5 km! The silkworm peeled its cocoon for the last time and became a pupa. After about 10 days, they come out of the cocoon in the form of silkworm moths. After cocoon emergence, the female moth smells from the tail to lure the male moth to mate, and the male moth dies after mating. A female moth can lay about 500 eggs a night and then die slowly.
